jQuery POST请求始终返回Laravel 4找不到的404

Question

Every time I try to make a POST request with jQuery I keep receiving back the 404 error.

This is the UserController.php :

class UserController extends BaseController {

    public function signUp($username, $password, $email) {

        $user = new User();
        $user->setUsername($username);
        $user->setPassword($password);
        $user->setEmail($email);

        return 'OK';
    }
}

And this is the routes.php :

Route::get('/signup', function(){

    return View::make('signup');
});

Route::post('/signup/{username}/{password}/{email}', 'UserController@signUp');

I always receive this error:

POST http://192.168.0.102/webname/public/signup 404 (Not Found)

Why is that? If I try to navigate to http://192.168.0.102/webname/public/signup the page is loaded and the signup form is shown.

Answer 1

You're are using a "GET" type route.

Let me explain.

If you want to use a route like /route/{something}/{different} you have to manualy generate an URL matching that route.

URL::route('route', $something, $different)

Variable passed thought POST method are only available in the HTTP Headers.

So you can't call Route::post('/route/{variable}') by passing variable though POST method. Only with Route::get().

To get your variable with POST use

Input::get('your_variable_name')

in your controller action.

Sorry for my bad english... A little bit tired, and I'm french too !

You are defining

Route::post('/signup/{username}/{password}/{email}', 'UserController@signUp');

But trying to access: /webname/public/signup.

That pattern does not exist for POST, but just for GET.

I had some troubles that were related to this discussion and in my opinion did not merit their own post: jQuery post requests kept getting handled by my Laravel get controller.

My routes:

Route::controller('/test','TestController');

In my view :

<script>
    $(document).ready(function() {          
        jQuery.ajax({
            type:'post',
            url: '/test/x/',
            success: function (response) {
                alert(response);
            }
        });
    });
</script>

My Controller:

public function getX() {
    return 'Get';
}     
public function postX() {
    return 'Post';
}

On page load, I expected to see an alert reading "Post"... but instead I kept seeing "Get". Laravel was routing the post request to the get controller.

Solving this had to do with the trailing slash. Apparently, Laravel interpreted "/test/x/" as a GET route, but "/test/x" as a POST route. So the lesson is that Laravel routing can be subtle. Hope that helps clarify the discussion a bit.
